Chelsea manager Jose Mourinho has said that he understands that many of his players are frustrated at being left out of the starting XI.

The Blues beat Arsenal 2-0 in midweek, but Mourinho has made nine changes from that side.

The Portuguese told BT Sport that his players must use their frustration as a catalyst to prove him wrong.

"At the moment the mentality is right and I understand some people who aren't playing are frustrated, but they must turn that frustration into the right mentality on the pitch," Mourinho said in the build-up to today's match at Newcastle.

"All of them are difficult decisions, because all of the boys against against Arsenal had a magnificent match, but every decision is a fair decision.

"The team is playing well. We had a fantastic October, but October is over and we have a very difficult match."
